"Ok wait a second, DNF is now using an in house engine (yeah that'd be the 4th change)? As in 3D Realms engine? or does he mean Unreal 3 technology or some type of derivitave?

Also 50, i'm pretty sure your right, i listened to the mp3 and the context of the whole conversation would make alot more sense."DNF does not use the Unreal engine 3 technology nor does it use a completely inhouse engine. 3D Realms still use the Unreal engine.

But they have rewritten every sub-system of it including the renderer, except the Unrealed editor, the netcode and maybe the Unrealscript language, everything else is 3D Realms code. They are hiring artists now because finaly it is the content and not the technology wich is the bottleneck. They are basicliy finished with the engine and will not add any features wich delay the game. They are now focusing on content development, bug fixes and optimization.

The renderer is a full Directx 9 renderer and is considered to be visually competetive. 3D Realms has said that they are either gonna ship on this engine or cancel the game. There has only been one engine switch from Quake 2 to Unreal. The rest are just different versions of the Unreal engine.
